Availability of rotifera natural food needs to be increased in line with the increasing need for larvae feed in fish hatchery production activities. This study aims to analyze the effect of different feeds on the growth rate of rotifers (Branchionus plicatilis). This research was conducted in December 2018 to January 2019 at the Jepara Brackishwater Aquaculture Center. This study used a completely randomized design with 4 treatments and 3 repetitions, namely control (N. ocullata), treatment 1 (N. ocullata + bread yeast), treatment 2 (N. ocullata + scott emultion), treatment 3 (N. ocullata+ fish powder). The dosages of each feed were 170,000 cells / ind N. ocullata, 0.5 g / 106 rotifera bread yeast per day, 6 µg / ind scott emultion, and 0.3 g /106/ind fish powder. Feeding is done twice a day in the morning and evening. The test plankton used was 15 ind / ml Branchionus plicatilis. Rotifera culture was carried out for 6 days and the population of rotifers was observed every day before feeding. Analysis of water quality was also carried out including DO, salinity, pH, temperature, and ammonia. The rotifera growth rate is analyzed through the number of individuals produced during the culture period. The results showed that treatment 3 (N. ocullata + fish powder) was the best treatment. The results of the ANOVA test showed that different feeding variations for each treatment had a significant effect (P <0.05) on the rotifera growth rate.

Trigona is a stingless bee that protects itself by swarming and biting. The bee products that are widely used in addition to honey are propolis, wax and the royal jelly. Trigona bee is one of potentially honey producer that has not been widely known. One species of trigona bee found in Bali is the Trigona laeviceps. They are nested in the crevices of rocks or in the tree trunk. This research aims to determine variations of entrance shapes, food storage, and brood cells of T. laeviceps from different altitudes. Colonies were observed in the Laboratory of Animal Taxonomy, Biology Department, Faculty of Mathematics and Basic Sciences, Udayana University, and nest entrance was analyzed in the Analytic Laboratory, Udayana University. Colonies were collected from bamboo nest in a tubular form and wooden nest from wooden boxes. Nest entrance is either flat or protruded out of the nest in an oval shape. The form of the entrance is not affected by the altitude. The nest entrance contained around 0,05 % flavonoids. The size and shape of pollen and honey pots volume was lightly lager in colonies collected from altitudes more than 400m above sea level (0.058 ± 0.04 mm³) than colonies collected from altitudes less than 400 m above sea level (0.035 ± 0.03 mm³). Royal jelly pots and brood cells have also similar shapes, but the volume is larger in colonies collected from altitudes less than 400 m above sea level (0.015 ± 0.07mm³) compared to altitude of more than 400 m above sea level (0.011 ± 0.02 mm³ )
